2. Add the following details and save the file:

{
  "mcpServers": {
    "mssql": {
      "command": "npx",
      "args": [
        "-y",
        "mcp-node-mssql"
      ],

Claude Code

See the official Claude Code docs for more information.

You can add a new MCP server from the Claude Code CLI. But modifying the json file directly is simpler!

1. Open the Claude Code configuration file (it should be in ~/.claude.json).
2. Find the projects > mcpServers section and add the following details and save the file:

{
  "projects": {
    "mcpServers": {
      "mssql": {
        "command": "npx",
        "args": [
          "-y",
          "mcp-node-mssql"
        ],
        "env": {
          "DB_HOST": "localhost",
          "DB_PORT": "1433",
          "DB_USERNAME": "<username>",
          "DB_PASSWORD": "<password>",
          "DB_DATABASE": "<database>"
        }
      }
    }
  }
}

Issues and Troubleshooting

Before doing anything else, please make sure you are running the latest version!

If you run into problems using this MCP server, please open an issue on GitHub!

Development

Installation

npm install

Build

npm run build

Running the Development Server Locally

To test your local development version of the MCP server rather than using the published package, follow these steps:

1. Build the project:

npm run build

2. Create or modify your mcp.json file to reference your local build:

{
  "mcpServers": {
    "mssql": {
      "command": "node",
      "args": [
        "/path/to/your/local/mcp-node-mssql/dist/index.js"
      ],
      "env": {
        "DB_HOST": "localhost",
        "DB_PORT": "1433",
        "DB_USERNAME": "<username>",
        "DB_PASSWORD": "<password>",
        "DB_DATABASE": "<database>"
      }
    }
  }
}

3. Place this mcp.json file in one of the following locations:

   • For Cursor: In your home directory (~/.cursor/mcp.json) or in your project directory (.cursor/mcp.json)
   • For Windsurf: Use the MCP Configuration Panel to add the custom server

4. Restart your AI assistant (Cursor or Windsurf) to load the new configuration.

This allows you to instantly test changes to the MCP server without having to publish a new version.
